VIDEO IMAGE SIZE SCALING Abstract of the Disclosure The size of an object in the field of view of a television camera or other device which can create an image of an object is determined by generating a calibrated grid for a video display in response to a measurement of the distance between the image creating device and the object itself. Both the object and the grid may be displayed on a video display means in such a manner that the object is overlaid with the calibrated grid. The length of the lines in the calibrated grid or the distance between points in the calibrated grid, as actually displayed, will be representative of a particular distance and thus an observer viewing the video display can determine the actual size of the object by using the calibrated grid to actually measure the object .
